Father George Tyrrell S.J. (February 6, 1861 – July 15, 1909), was a priest and Modernist scholar whose attempts to interpret Catholic teaching in the context of modern knowledge made him a key figure in the Modernist controversy within the Roman Catholic Church in the late 19th century.

Tyrrell was born in Dublin, Ireland and brought up as an Anglican. He converted to Roman Catholicism in 1879. Joining the Jesuits in 1880, Tyrrell was ordained to the priesthood in 1891. He argued, counter to Church teaching, that the Pope must not be an absolute autocrat in the Church, but rather, a "spokesman for the mind of the Holy Spirit in the Church", the "Base Community" as he termed it, of the laity.

Tyrrell argued that most biblical scholarship and devotional reflection, like the quest for the "historic" Jesus involves elements of self-conscious self-reflection. His famous image, criticizing Adolf von Harnack's human view of Scripture is of peering into a well, in which we see our own face reflected in the dark water deep below:

"The Christ that Harnack sees, looking back through nineteen centuries of Catholic darkness, is only the reflection of a Liberal Protestant face, seen at the bottom of a deep well." [1]

Tyrrell suffered under Pope Pius X because he upheld "the right of each age to adjust the historico-philosophical expression of Christianity to contemporary certainties, and thus to put an end to this utterly needless conflict between faith and science which is a mere theological bogey". Tyrell was expelled from the Jesuits in 1906 and suspended from the sacraments the following year. He was given extreme unction on his deathbed in 1909, but denied burial in a Catholic cemetery. A priest who was present at the burial made a sign of the cross over Tyrrell's grave. For this act he was suspended a divinis by Bishop Peter Amigo of Southwark [2].
